kow [346]

<h3><u>The following events are identified as chemical weathering:</u></h3>
  • The minerals in a marble statue react with water to form acids and pores in the structure.

When the weathering process occurs due to <em>chemical reaction</em>, then it is considered as chemical weathering.

In <em>the first case</em>, minerals of marble statue are <em>reacting</em> with water to cause weathering. In the <em>second case</em>, due to the <em>acidificaion reaction</em>, the change of the color has happened after exposure to the repeated rains.

  • Industrial runoff forms cracks in a rocky structure in its path.

<em><u>Reason:</u></em>

When the rock is broken into simple pieces <em>without any chemical reaction </em>it is considered as mechanical weathering.

In the <em>first cause</em>, due to the <em>abrasion</em> caused by the strong waves, weathering has happened, in the <em>second case</em> industrial run off may be of varying temperature and thus may cause <em>heating or cooling</em> of the rock and causes weathering.
